What size is a 1 Carat Diamond?
It is crucial to choose the right size and shape diamond. An engagement ring, which is the symbol of love and commitment for every woman, is the most important piece on a jewellery set. Price of a diamond is determined by its form, colour, clarity, and carat.

It’s true that most people opt for a 1 Carat Diamond as their engagement ring. Why? It’s because you can’t go wrong with a 1ct-sized diamond in any shape or size. It is important that you understand that diamonds’ prices rise exponentially, not linearly. A 2 carat diamond won’t cost twice as much as a 1 carat. It will be significantly higher.

The larger the diamond, the more expensive it will be. A diamond of 6 carat can be 20 times more expensive than one of 1 carat, depending on its quality.

Because of the cut proportions of two diamonds, their carat weights and shapes may look different. Due to its greater depth, a deeper cut diamond would be smaller in diameter than an ideal cut. These differences are not usually significant, but you can notice them. While a well-cut diamond may have a slightly lower carat than a deeply-cut diamond, it can still have a greater diameter. It appears larger because of this.

Based on the shape of the stone, two diamonds of equal weight might appear very different in size. A 1 carat marquise will often appear larger than an 1 carat round.
